Suggest Planning Software For Use With Brian Tracy's System

Okay, I’ve decided to try organizing myself by the following princples:

Here’s a snippet:
"There are different lists that you need for different purposes. First, you should create a master list on which you write down everything you can think of that you want to do some time in the future. This is the place where you capture every idea that comes to or every new task or responsibility that comes up. You can then sort out the items later.

Second, you should have a monthly list that you make up at the end of the month for the month ahead. This may contain items transferred from your master list.

Third, you should have a weekly list where you plan your entire week in advance. This is a list that is under construction as you go through the current week.

Finally, you transfer items from your monthly and weekly lists onto your daily list. These are the specific activities that you are going to accomplish that day."

Okay. I had been using Mindomo in the past for brainstorming and business planning, but I wonder if any Doper productivity gurus have input for me.

What OS? I use Omnifocus on OS X, iPad and iPhone, and it’s marvelous for GTD. Mr. Tracy’s system sounds similar, although not the same.

For me, I find that having my list on both a big screen and a phone is great - I can use the laptop version to organize and put in details, and the phone or iPad when I am on the go.

If you have an iPhone, there are a number of decent GTD/to-do applications, some of which are free. I’m sure the same is true of Android.

I use my netbook running XP for most of my business. Probably be moving to Win7 before long.
If I’m not using the netbook, I’m probably not working per se.
